WTB: Medium Case 3.64 or 3.73 LSD

[MPLFoster]

Looking for an LSD for my 325i. Either S3.64 or S3.73...maybe a 3.46 or 3.91 LSD if the price is right, but those ratios are on either end of the spectrum for me. Not really interested in a 4.10 since i intend to do some serious distance driving in the future.

Let me know what you have.

Thanks R3V.

Hoping something local pops up. Not trying to pay $100 for shipping...
